To allwhom it may concern:

Be itknown that I, J oHN AULD, a citizen resident of Chicago, in the county of Cook, State of Illinois,

have invented certain new and useful 1m provements in Fountain Brushes, of which the followmgis a specification. My invention relates to fountain brushes,

particularlyto' thattype for marking on boxes, bales, packages or containers. 7

Among. the mportant obp-cts ofmy in ventlon are: toprovlde improved construc tion Which will prevent leakage especially at the outlet valve mechanism, of ink which will eventually findits way to the. outside of the brush. and soil the hands of the user; to

provide improved. adjustable stopper .or valve mechanism for controlling the outflow 'of writingfluid from the brush body; to: provide improved arrangement which will enable the ready substitution of one form of "handle and ink container 10. in the marking point'for' another; toprovide. simple and practicalfarr'angement whichwill' enable the various parts-to bereadily as r sembled'or taken part; and ingeneral, to. 1 provide a light, simple, ;.neat" and easily controlled. fountain ."br'ush handledand structure.

, fhe brush body comprises a combined a'length of tubejprovided at one end'with a cap 11 and at its other end with a fitting 12" for supporting the valve and marking. mechanism designated as whole by 13'. In

Figs. 1 and 2, one form of fluid discharge controlling mechanism is shown.v The fitting l2 has the threaded end 14 which receives the nozzle basel5.

overflow orbackfiow ofink'. If, after a pe 90 pen the, port 20 5 riod of use, the brush is raised, unused ink may flow back along the brush structure and the frame 22, but such ink will be accumulated in the well formed by the tube 21 and the base 15, and then when the brush is again turned to its operative position, this ink will flow down to be used. Some ink may also leak past the threads which connect the cap 19 with the base 15, but here again the well will receive the leakage and it will utiinately be used for marking purposes.- This will prevent any of the ink from reaching the'handle part or body of the brush where it could soil the hands of the user.

'To enable the userto adjust more accurately for the outflow of ink, the fitting 12 has gauge markings 29 thereon (Fig. 1), the co-operation of the inner end of the arm 19 with these gauge marks informing the user to what degree the ink port 20 is open. As shown iuhig. 1, the end of the fitting 12 is polygonal so that a wrench may be applied for applying or removing the fitting with reference to the container 10. On the sides of this polygonal section, I have shown numerals applied which in this case serve as gauge indications fo co-operating with the arm 2 In Figs. 5, 6, 7 and 8, I have shown a modified construction. Here, like in the constructions of Figs. 1 and 2, the nozzle structure base 15 is secured to the threaded end of the fitting 1-2 and at its end has the valve pin or cone 17 surrounded by passage ways 16, and the nozzle cap 19threading on to the base member 15 and having the port 20 for co-operating with the valve pin or cone. This modification 'also'has a tube 21 which, however, instead of being rigidly secured to the base 15 has threaded engagement with a flange 30 extending from the base 15 outside of and spaced away from the ba'seend which receives the nozzle cap. This outer flange forms a cup for receiving back flow or overflow of ink or any ink that may escape between the threads which hold the cap to the nozzle base. Between the fitting 12 and the abutment flange 31 on the tube 21 is inserted the compression spring 32 for locking the tube against accidental rotation.

The nozzle cap in the modified structure has the arms '33 and '34; extending therefrom well through the'tube 21 so as to receive between them the block 35 of. felt or other suitable material for conveying ink. As shown, this marking block or point is seated in the U-shaped frame 36 where it may be held in place by a screw 37 extendingthrough the yoke of the frame'and threading into the block. The outwardly deflected ends 38 and 39 on the U-fra'me extend outwardly through notches 40 and 4&1 formed in the end of the tube 21. With this arrangement, turning ofthe tube 21 will be communicated by the extensions 38 and 39 to the marking point structure and from there to the arms 33 and 34 extending from the nozzle cap, so

as in the construction of Figs. 1 and 2, bristles being usually used when marking is done on rough surfaces while a felt or snnilar marking tip is provided where marking is to be done on smoother material. I

It is evident that instead of the cap 11 at one end of the brush body, a fitting 12 can be provided to which a valve and marking point structure can be applied so that there would be a double ended brush, one end of which could be used for marking on rough surfaces .and the other end, for marking ,on smooth surfaces, Theoverflow and surplus ink receiving well would then form an 1 p'ortant part as they would prevent flowingof ink from the upper marking end to the brush body and to the handsof the user. .Other changes and modifications are," of

course, possible which would still come within the scope of my invention. 1 do not,

therefore, desire to be limited to the exact" construction, arrangement and operation shown and desired. I "claim as follows: 7 1. In a fountain brush of the class described, the combination of an ink container, a nozzle base at one end of said container, a cap rotatable on said base, valve mechanism controlled during rotation of said cap on said base for regulatingthe flow of ink "from said container, a tube extending from said base and surrounding said cap, extensions on said cap, a marking point supporting frame extended into said tube to engage withjsaid extensions, a "marking point held: by said frame, and an arm extending from said frame along side the out-side of said tube, said arm enabling turning of said marking point supporting frame and thereby turning of said cap by virtue of engagement-of said frame with said extensions.

2. In a fountain brush of the class scribed, the combination of a tubular ink container, a nozzle base sec'ured'a't one end of said container, a nozzle cap having threaded engagement with said base, valve mechanism controlled upon turning of 'said cap on saidbase to regulate the'flow of ink from said container, a tube extending from its said base around said cap, extensions on said 7 cap, a marking point supporting frame ex-- tended intosaid tube and engaging between said extensions whereby turning of said said frame may be frame will turn said cap-to effect adjustment of the ink flow, a marking point held by said frame and extending from the'end of the tube, and an arm extendin from said frame along the outside of saic tube and having spring-locking 'engagement'with said tube, said arm serving as a handle whereby rotated and said cap rotated to adjust the flow of ink, said tube also serving or backfiow ink.

3. In a fountain brush, the combination of an ink container forming a handle, a base on said container having an outlet opening, a valve extending from said base, a cap movable on said base and having aport for cooperating with said valve to control the outflow of ink from said container, extensions on said cap, and a marking point held between said extensions and prevented thereby from turning relative to the cap, said marking point when turned causing said cap to be rotated to thereby control co-operation of the valve and port. I

at; In a fountain brush, the combination of a reservoir. for ink, a valve base on said res-.

ervoir, a valve on said base, saidbase being apertured for the flow of ink, a cap threaded on said base and having a port for co-operating with the. valve to regulate the. flow of ink, a tube extending from'said, base and as a well forstoring overflow from said the tube, turning of said handle around said said port and valve 8 s forming anink-tight W611 with said base at catching and retaining surplus ink, a frame extendingfrom said cap, arbrush supported by said frame, an extension on said .frame to the exterlor of said tube forming a handle whereby said frame may be rotated to in turn rotate said cap and relatively adjust said valve and port to regulate the flow of ink.v V

5. In a fountain brush, the combination of a reservoir forink, a base on said reservoir,

a valve on said'base, ink apertures in said base adjacent said valve, a cap threadedly engaging said'base and having a port for 00- operating with said valve to regulate the flow of ink, a tube secured to and extending ink tight well to catch and retain surplus ink, a' frameconnected with and extending from said cap through said tube, a brush supported by said frame, and an operating handle formed by extending partof'said c frame outward andagainst the outside of tube causing turning ofsaid frame and said cap wherebyadjustment is effected between and the flow of ink regulated. r
